Thermal stability order of alkaline earth metal hydrides ??

Answers

Answered by sudhirhaldkar2980

Answer:

As we move from top to bottom in a group the size of the alkali metals increases, thereby the bond dissociation energy decreases hence it requires less energy to decompose so thermal stability also decreases.. So the order of thermal stability of IA group elements is LiH > NaH > KH > RbH.
